The specific embodiment
The present invention is further detailed explanation in conjunction with the accompanying drawings and embodiments now, and these accompanying drawings are the schematic diagram of simplification, basic structure of the present invention is only described in a schematic way, so it only shows the formation relevant with the present invention.
As depicted in figs. 1 and 2, a kind of distilling apparatus, comprise the pump 10 connecting successively, heater 20, pressure-reducing valve 30, pressure-regulating device 40 and knockout tower 50, in the present invention, pressure-regulating device 40 comprises the housing 41 of cylindricality, in housing 41 one end, be provided with the hand-hole 42 being communicated with pressure-reducing valve 30, in housing 41, in hand-hole 42 one end, being provided with can be along the outlet 43 of housing 41 radial elastic dilation, in housing 41, in outlet 43 one end, be provided with steel ball 44, steel ball 44 is connected with Compress Spring 45, the diameter of outlet 43 is less than the diameter of steel ball 44, steel ball 44 can snap onto in outlet 43 under Compress Spring 45 effects, outlet 43 is connected with the charging aperture 51 of knockout tower 50 upper side edges.During distillation, feed liquid is after pump 10 pressurizations, send in heater 20 and heat up, the temperature that makes feed liquid is boiling point under knockout tower 50 setting pressures higher than it, by pressure-regulating device 40, automatically regulate pressure-reducing valve 30, make feed liquid become superheat state and enter knockout tower 50, its sensible heat being above the boiling point (is that object is not when chemical change or phase change occur, temperature raises or reduces needed heat and is called sensible heat) feed liquid is vaporized, after this process, the vapour-liquid two-phase of balance in knockout tower 50 after separation, respectively from knockout tower 10 tops, bottom discharges.In automatic Regulation process, pressurization due to pump 10, feed liquid is larger at the pressure of pressure-reducing valve 30 import departments, need by regulating, the pressure of Jiang Qi import department reduces to the outlet pressure of a certain needs, and the pressure in exit regulates automatically by the pressure ratio in pressure-regulating device 40 and knockout tower 50 is rear, be that pressure-regulating device 40 one end connect pressure-reducing valve 30, the other end connects knockout tower 50, utilizes in pressure-regulating device the motion of the steel ball 44 in 40 to control feed liquid and is entering in knockout tower 10 under corresponding pressure.Concrete, the hand-hole of pressure-regulating device 40 42 is connected with the exit of pressure-reducing valve 30, the outlet of pressure-regulating device 40 43 is connected with the charging aperture 51 of knockout tower 50, pressure in known knockout tower 50 is P1, the pressure-reducing valve 30 needed pressure in exit are P2, therefore, the pressure P 3 providing when Compress Spring 45 meets P3≤P2-P1, preferred P3=P2-P1 in the present invention, now, pressure balance, steel ball 44 makes a decision in the end of outlet 43, and feed liquid can enter in knockout tower 50 through exporting 43 from hand-hole 43; If P3 > is P2-P1, steel ball 44, under the effect of Compress Spring 45, is squeezed in outlet 43, will export 43 sealings, makes feed liquid enter knockout tower from exporting 43.In still-process, for corresponding feed liquid, pressure P 2 to its distillation is fixed with P1, therefore, only need to control the pressure P 3 of Compress Spring 45, can automatically regulate feed liquid to enter knockout tower 50 under this corresponding pressure, without regulating manually pressure-reducing valve 30, while distilling different feed liquids, only need to change corresponding Compress Spring 45.Whether in the present invention, by Compress Spring 45, control steel ball 44 enters in outlet 43, thereby regulate the exit of pressure-reducing valve 30 to meet needed distillation pressure, pressure degree of regulation to pressure-reducing valve 30 is high, guarantee the temperature of liquid in heater, make this temperature meet the sensible heat of feed liquid vaporization, thereby guarantee the effect of vapor-liquid separation.
Preferably, hand-hole 42 is notch cuttype with the junction of outlet 43, and the diameter of outlet 43 is less than the diameter of hand-hole 42, when steel ball 44 is squeezed into outlet 43 when interior, can well feed liquid be blocked in outside outlet 43, and sealing function is good.
Further, when steel ball 44 is squeezed into outlet 43 when interior, be subject to the extruding of steel ball 44, outlet 43 radially produces and expands, for avoiding housing 41 distortion, can establish in housing 41 inwalls and outlet the clearance groove 46 of a loop between 43 outer walls, between clearance groove 46 and housing 41, offer and pore 42 that housing 41 outsides are communicated with.Housing 41 can adopt rigid material to make, and the outer wall of outlet 43 can adopt elastomeric material, and by clearance groove 46 and pore 42, the outer wall of outlet 43 can not make housing 41 distortion in expansion and recovery process.
For convenience of pressure-regulating device 40 is connected with pressure-reducing valve 30, can between hand-hole 42 outer walls and housing 41 inwalls, establish U-shaped buckling groove 48 in the end of housing 41, the exit of pressure-reducing valve 30 is snapped onto in buckling groove 48, hand-hole 42 can with pressure-reducing valve 30 internal communication.
In the present invention, in knockout tower 50, be provided with column plate 52, downflow weir 53, seal pot 54 and downspout 55 from top to bottom, column plate 52 and downflow weir 53 are positioned at the upside of charging aperture 51, and seal pot 54 and downspout 55 are positioned at the downside of charging aperture 51.Can make each self-separation of vapour phase and liquid phase from top, the bottom of knockout tower, discharge respectively.
Preferably, the seal pot 54 in the present invention is spill, and the degree of depth of seal pot 54 depressions is 50～150mm.Recessed seal pan ．． 54 not only can cushion the hydraulic shock that downspout 55 flows down, the liquid splash that minimizing causes because of impact, and when capacity of returns is very little, also there is good fluid-tight effect, can make flow liquid flow into equably bubbling area (being that liquid phase flows through from seal pot 54 region that downspout 55 outlets arrive), guarantee separating effect simultaneously.
Above foundation desirable embodiment of the present invention is enlightenment, and by above-mentioned description, related personnel can, within not departing from the scope of this invention technological thought, carry out various change and modification completely.The technical scope of this invention is not limited to the content on description, must determine technical scope according to claim scope.
